At a certain time, the difference between the temperature in New York City and in Boston was 7 degrees Celsius.

The difference between the temperature in Boston and in Chicago was also 7 degrees Celsius.

Was the temperature in New York City the same as the temperature in Chicago? Explain your answer.

No, the temperature in New York City and Chicago cannot be determined to be the same based on the information given. The given information states that the temperature difference between New York City and Boston is 7 degrees Celsius, and the temperature difference between Boston and Chicago is also 7 degrees Celsius. However, the absolute temperature values for New York City, Boston, and Chicago are not provided.

To determine if the temperature in New York City was the same as the temperature in Chicago, we need to compare the difference between the temperature in New York City and Chicago.

First, we know that the difference between the temperature in New York City and Boston was 7 degrees Celsius.

Next, we know that the difference between the temperature in Boston and Chicago was also 7 degrees Celsius.

If we add these two differences together, we get a total difference of 14 degrees Celsius (7 degrees from New York City to Boston + 7 degrees from Boston to Chicago). This means that the temperature in New York City was 14 degrees Celsius different from the temperature in Chicago.

Therefore, the temperature in New York City was not the same as the temperature in Chicago.

To determine if the temperature in New York City is the same as the temperature in Chicago, we need to compare the temperature differences between each city.

It is given that the difference between the temperature in New York City and in Boston is 7 degrees Celsius. Therefore, we can say that New York City's temperature is 7 degrees higher or lower than Boston's temperature, depending on the direction of the difference.

Additionally, we are given that the difference between the temperature in Boston and in Chicago is also 7 degrees Celsius. Based on this information, we can infer that Boston's temperature is 7 degrees higher or lower than Chicago's temperature, depending on the direction of the difference.

Now, if the temperature in New York City is higher or lower by the same amount as Boston's temperature when compared to Chicago's temperature, then the temperature in New York City would be the same as the temperature in Chicago. However, since we do not have this information, we cannot conclusively determine if the temperature in New York City is the same as the temperature in Chicago.

In conclusion, based on the information provided, we cannot definitively state whether the temperature in New York City is the same as the temperature in Chicago.
